Generator Rotor Inspection & Life Assessment

Many generator rotor components—including rotor bores, retaining rings, rotor tooth-top dovetails, and shafts—require close inspection and life assessment. This SI Webinar covers inspection techniques, including linear phased-array (LPA) ultrasonic dovetail inspections, as well as LPA inspections of rotor shafts for under-coupling cracking initiated by fretting fatigue. The presentation also discusses how to analyze inspection data for each of the above components.

Larry Nottingham holds a BS in Mechanical Engineering from the University of Pittsburgh, and has over 35 years of experience in design, maintenance, and nondestructive evaluation of turbines, generators, and other power plant equipment. He also has extensive experience in development and delivery of advanced nondestructive evaluation systems and procedures for numerous power plant applications, with emphasis on turbine and generator components and high-energy piping.

Scott Rau, PE has a MS in Structural Engineering from the University of California, Los Angeles. He has extensive experience in stress analysis, including finite element analysis and modeling of structures and components with linear or non-linear behavior; dynamic system response and time history analysis; and transient thermal elastic-plastic analysis. Rau has performed remaining life evaluations of over 50 high-energy piping systems, and of similar numbers of steam turbine and generator rotors.
